Question

por favor me ajudemmmmm ​

Answer 1

a)(4+i)+(-1-3i)+(-2+i)

(4+i)+(−1−3i)+(−2+i)

1.414213562

∣4−1−2+(1−3+1)i∣≈1.414213562

(b)(-7+5i)-(3-2i)

(−7+5i)−(3−2i)

(−7−3+(5−(−2))i)=−10

3-7-25

(-10+7i)=-10

(−10+7i)=−10

-10+7i-10

-10

(c)2+(3-1)+(-1+2i)+i

2+3-1+\left(-1+2i

Re(2+3-1-1+

Re(2+3−1−1+(2+1)i)=3

(d)2+3-1-1+\

Re(3+3i)=3

Re(3+3i)=3

3+3i3

3

3

−10 (d)4i−(1−3i)−(−2+i

1-3i4i

(1+(4−(−3))i−(−2+i))=3

-34

(−1+7i−(−2+i))=1

-2+i-1+7i

-2-117

(1+6i)=1

(1+6i)=1
